LOPEZ-REYMUNDO, Paulo et al. Non-invasive oxygenation methods in patients with COVID-19. Rev. mex. anestesiol. [online]. 2023, vol.46, n.4, pp.268-271.  Epub 26-Fev-2024. ISSN 0484-7903.  https://doi.org/10.35366/112298.

Since the start of the COVID-19 pandemic, the most frequent complications of this infection include pneumonia and Acute Respiratory Distress Syndrome. Hypoxemia and increased work of breathing are determining factors in adopting various non-invasive oxygenation therapeutic strategies in patients with COVID-19. It is important to know and describe the different modalities of non-invasive oxygen therapy, in order to preserve oxygenation and adequate respiratory work, the strategies described in the literature include: conventional nasal cannulas, high-flow nasal cannulas and non-invasive mechanical ventilation coupled with other support measures such as prone position, administration of schemes with steroids, immunomodulators and inhaled nitric oxide. Non-invasive oxygenation strategies by different methods are essential tools for the treatment of patients with moderate-severe COVID-19 pneumonia. It is necessary to evaluate the device to be used, since this disease has heterogeneous characteristics according to severity and time of evolution.
